KnowraNuclear isomerLinked fromLinked fromThe 9 pages that link to Nuclear isomer, each with the reason it gives.All 9Broader topic 2Related 5Narrower topic 1Compared with 1Nuclear shell modelBroader topic: Shell structure can hinder transitions, leaving excited nuclear states unusually long-lived.Nuclear stabilityCompared with: Metastable isomers show that persistence can depend on decay barriers, not just the ground state.NuclideBroader topic: It distinguishes nuclides further by nuclear energy state.Spontaneous fissionRelated: Some long-lived isomeric states provide cases for studying fission from metastable configurations.Gamma decayRelated: Long-lived isomers can release their stored excitation energy through delayed gamma decay.Gamma-ray spectroscopyRelated: Isomeric states can produce delayed gamma-ray cascades.RadionuclideRelated: Some radionuclides are metastable nuclear isomers that decay by releasing excess nuclear energy.Technetium-99mNarrower topic: Technetium-99m is a long-lived excited state of technetium-99.Collective modelRelated: Collective structure can help explain the spins, shapes, and decay paths of isomeric states.
